Abstract
Pre-clinical use of humanized mice transplanted with CD34+ hematopoietic stem and progenitor cells (HSPCs) is limited by insufficient engraftment with adult non-mobilized HSPCs. Here, we developed a novel immunodeficient mice based on NOD-SCID-Il2γc-/- (NSG) mice to support long-term engraftment with human adult HSPCs. As both Flt3L and IL-6 are critical for many aspects of hematopoiesis, we knock-out mouse Flt3 and knock-in human IL6 gene. The resulting mice showed an increase in the availability of mouse Flt3L to human cells and a dose-dependent production of human IL-6 upon activation. Upon transplantation with low number of human HSPCs from adult bone marrow, these humanized mice demonstrated a significantly higher engraftment with multilineage differentiation of human lymphoid and myeloid cells, and tissue colonization at one year after adult HSPC transplant. Thus, these mice enable studies of human hematopoiesis and tissue colonization over time and may facilitate building autologous models for immuno-oncology studies.

Abstract
Realizing the clinical promise of cancer immunotherapy is hindered by gaps in our knowledge of in vivo mechanisms underlying treatment response as well as treatment limiting toxicity. Preclinical in vivo model systems and technologies are required to address these knowledge gaps and to surmount the challenges faced in the clinical application of immunotherapy. Mice are commonly used for basic and translational research to support development and testing of immune interventions, including for cancer. Here, we discuss the advantages and the limitations of current models as well as future developments.

Abstract
Abstract
Triple-negative breast cancer (TNBC) is a particularly aggressive form of breast cancer with high risk of recurrence and approximately 22% rate of five-year survival when the disease becomes metastatic. Thus, understanding of mechanisms supporting metastatic colonization of distant organs is of critical importance for the development of new therapies and possibly improved outcomes. Syngeneic mouse models suggest the role of innate immune cells, particularly neutrophils, in support of metastatic dissemination of TNBC. However, it is not possible to study human cancer in immunocompetent mice. Furthermore, organoids or other 3D tissue models do not allow investigations of distant organs colonization with metastatic TNBC tumors. Here, we used humanized mice and patient-derived xenograft (PDX) from treatment naïve primary TNBC tumors to investigate the mechanisms that promote metastasis. NSG mice with transgenic expression of human hematopoietic cytokines SCF/GM-CSF/IL-3 were engrafted with human CD34+ hematopoietic progenitor cells (HPCs) to generate humanized (h)NSG-SGM3 mice. All PDX tumors grew after orthotopic implantation at week 8-12. The presence of distant metastasis was determined by macroscopic evaluation of distant organs and further confirmed by E-cadherin and cytokeratin 19 expression using polychromatic immunofluorescence on frozen tissue section. Among ten PDX tumors tested, four did not develop metastasis, four developed only lung metastasis and two developed multi-organ metastases (lung and liver). We find that different TNBC PDX tumors have different metastatic potential. Their metastatic potential is linked with differences in cellular composition and transcriptional signatures at the level of the primary tumor. Interferon Response signature is enriched in primary TNBC PDXs with metastatic potential, while non-metastatic primary tumors display a TNF signature as well as allograft rejection signature. Furthermore, liver metastases were enriched in myeloid transcripts. Thus, our model enables mechanistic and pre-clinical studies of human TNBC metastasis.

Abstract
Abstract
Metastasis is a major risk factor for poor melanoma outcome, but mechanisms supporting distant organ colonization by melanoma are not fully understood. Here, we found that metastatic melanoma tumors from patients are infiltrated by CD33+ myeloid cells. To determine the role of CD33+ cells in melanoma metastasis, we used NSG mice humanized by engraftment of human CD34+ hematopoietic progenitor cells and transgenic expression of human hematopoietic cytokines SCF/GM-CSF/IL-3 (SGM3). Humanized (h)NSG-SGM3 mice enabled development of human CD33+ myeloid cells in the bone marrow and peripheral tissues, and when implanted subcutaneously with human melanoma cell line, supported melanoma colonization of the spleen, liver, lung, and kidneys. Melanoma growth in distant organs was dependent on host SGM3 expression and facilitated by human CD33+ myeloid cells. Deeper characterization attributed this activity to a rare human IL-3- and SCF-dependent CD33+CD11b+CD117+ progenitor cell subset comprising <4% of the total CD45+ leukocyte population. Metastatic tumor-infiltrating CD33+ cells from patients and hNSG-SGM3 mice showed converging transcriptional profiles. Single-cell RNAseq analysis identified a gene signature of a KIT/CD117 expressing CD33+ subset that correlated with decreased overall survival in TCGA melanoma samples. Thus, human CD33+CD11b+CD117+ myeloid cells facilitate metastatic colonization of distant organs by melanoma, representing a novel candidate biomarker as well as a therapeutic opportunity for metastatic melanoma.

Abstract
Metastasis of melanoma significantly worsens prognosis; thus, therapeutic interventions that prevent metastasis could improve patient outcomes. Here, we show using humanized mice that colonization of distant visceral organs with melanoma is dependent upon a human CD33+CD11b+CD117+ progenitor cell subset comprising <4% of the human CD45+ leukocytes. Metastatic tumor-infiltrating CD33+ cells from patients and humanized (h)NSG-SGM3 mice showed converging transcriptional profiles. Single-cell RNA-seq analysis identified a gene signature of a KIT/CD117-expressing CD33+ subset that correlated with decreased overall survival in a TCGA melanoma cohort.

Abstract
Abstract
The interaction between various components in the tumor environment plays a pivotal role in tumor development, migration and metastasis. While the 2-dimensional (2D) in vitro culture methods fail to assimilate the complexity of tumor microenvironment, the 3D multicellular tumor spheroids support co-culture conditions and allow a more physiologically relevant environment. We are working to establish such 3D model to investigate the molecular mechanisms regulating the interactions between human cancer cells such as melanoma or breast cancer, myeloid cells and T cells. Spheroids were developed using hanging drop technique with multiple cancer cell lines, dermal fibroblasts and immune cells. Preliminary experiments were carried out to determine the optimum conditions for spheroid formation. Spheroid formation occurred within 72 hours and their integrity was maintained throughout the experiments. Immunofluorescence analysis of spheroid cryosections showed a homogeneous distribution of fibroblasts in spheroids. Addition of purified blood CD14+ blood monocytes to the mixture of cancer cells and dermal fibroblasts enabled monocyte integration into spheroids. Adding melanoma specific CD8+ T cells to tumor spheroids formed by melanoma cell line (Me275), dermal fibroblasts and monocytes resulted in homogeneous infiltration and increased number of cell death. Addition of PBMCs to the mix of breast cancer cells and fibroblasts enabled the discrimination of spheroids into two groups, tumor spheroids with immune cells at the margin preferentially located at tumor margin and tumor spheroids with infiltrating immune cells. These preliminary observations resemble those from our in vivo models of humanized mice, where different tumor xenografts show different level of immune cell infiltration. Thus, our 3D model might allow the classification of tumor cells based on immune cell infiltration and could potentially be used to assess the distribution of immune infiltrates and the interaction of cancer cells with immune compartments.

Among 11 PDX tumors tested, five did not develop metastasis, four developed only lung metastasis and two developed multi-organ metastasis (lung and liver). Transcriptional profiling with RNAseq revealed significant differences in the immune landscape of primary and metastatic tumors. In particular, liver metastases were enriched in myeloid and plasma cell transcripts. Further analysis is ongoing to uncover specific pathways involved. Thus, our model enables mechanistic and pre-clinical studies of human TNBC metastasis.

Abstract
Dendritic cells (DCs) are critical for the launching of protective T cell immunity in response to viral infection. Viruses can directly infect DCs, thereby compromising their viability and suppressing their ability to activate immune responses. How DC function is maintained in light of this paradox is not understood. By analyzing the susceptibility of primary human DC subsets to viral infections, we report that CD141+ DCs have an innate resistance to infection by a broad range of enveloped viruses, including HIV and influenza virus. In contrast, CD1c+ DCs are susceptible to infection, which enables viral antigen production but impairs their immune functions and survival. The ability of CD141+ DCs to resist infection is conferred by RAB15, a vesicle-trafficking protein constitutively expressed in this DC subset. We show that CD141+ DCs rely on viral antigens produced in bystander cells to launch cross-presentation-driven T cell responses. By dissociating viral infection from antigen presentation, this mechanism protects the functional capacity of DCs to launch adaptive immunity against viral infection.

Abstract
The targeting of vaccine antigens to antigen presenting cells (APC), such as dendritic cells (DCs), is a promising strategy for boosting vaccine immunogenicity and, in turn, protective and/or therapeutic efficacy. However, in vivo systems are needed to evaluate the potential of this approach for testing human vaccines. To this end, we examined human CD8(+) T-cell expansion to novel DC-targeting vaccines in vitro and in vivo in humanized mice. Vaccines incorporating the influenza matrix protein-1 (FluM1) antigen fused to human specific antibodies targeting different DC receptors, including DEC-205, DCIR, Dectin-1, and CD40, elicited human CD8(+) T-cell responses, as defined by the magnitude of specific CD8(+) T-cells to the targeted antigen. In vitro we observed differences in response to the different vaccines, particularly between the weakly immunogenic DEC-205-targeted and more strongly immunogenic CD40-targeted vaccines, consistent with previous studies. However, in humanized mice adoptively transferred (AT) with mature human T cells (HM-T), vaccines that performed weakly in vitro (i.e., DEC-205, DCIR, and Dectin-1) gave stronger responses in vivo, some resembling those of the strongly immunogenic CD40-targeted vaccine. These results demonstrate the utility of the humanized mouse model as a platform for studies of human vaccines.

Abstract
Enzyme replacement therapy (ERT) is an effective treatment for several lysosomal storage disorders (LSDs). Intravenously infused enzymes are taken up by tissues through either the mannose 6-phosphate receptor (M6PR) or the mannose receptor (MR). It is generally believed that M6PR-mediated endocytosis is a key mechanism for ERT in treating LSDs that affect the non-macrophage cells of visceral organs. However, the therapeutic efficacy of MR-mediated delivery of mannose-terminated enzymes in these diseases has not been fully evaluated. We tested the effectiveness of a non-phosphorylated α-galactosidase A produced from moss (referred to as moss-aGal) in vitro and in a mouse model of Fabry disease. Endocytosis of moss-aGal was MR-dependent. Compared to agalsidase alfa, a phosphorylated form of α-galactosidase A, moss-aGal was more preferentially targeted to the kidney. Cellular localization of moss-aGal and agalsidase alfa in the heart and kidney was essentially identical. A single injection of moss-aGal led to clearance of accumulated substrate in the heart and kidney to an extent comparable to that achieved by agalsidase alfa. This study suggested that mannose-terminated enzymes may be sufficiently effective for some LSDs in which non-macrophage cells are affected, and that M6P residues may not always be a prerequisite for ERT as previously considered.

Abstract
The mechanisms by which microbial vaccines interact with human APCs remain elusive. Herein, we describe the transcriptional programs induced in human DCs by pathogens, innate receptor ligands and vaccines. Exposure of DCs to influenza, Salmonella enterica and Staphylococcus aureus allows us to build a modular framework containing 204 transcript clusters. We use this framework to characterize the responses of human monocytes, monocyte-derived DCs and blood DC subsets to 13 vaccines. Different vaccines induce distinct transcriptional programs based on pathogen type, adjuvant formulation and APC targeted. Fluzone, Pneumovax and Gardasil, respectively, activate monocyte-derived DCs, monocytes and CD1c+ blood DCs, highlighting APC specialization in response to vaccines. Finally, the blood signatures from individuals vaccinated with Fluzone or infected with influenza reveal a signature of adaptive immunity activation following vaccination and symptomatic infections, but not asymptomatic infections. These data, offered with a web interface, may guide the development of improved vaccines.

Abstract
Dendritic cells (DCs) play the central role in the priming of naive T cells and the differentiation of unique effector T cells. In this study, using lung tissues and blood from both humans and humanized mice, we analyzed the response of human CD1c(+) and CD141(+) DC subsets to live-attenuated influenza virus. Specifically, we analyzed the type of CD4(+) T cell immunity elicited by live-attenuated influenza virus-exposed DCs. Both DC subsets induce proliferation of allogeneic naive CD4(+) T cells with the capacity to secrete IFN-γ. However, CD141(+) DCs are uniquely able to induce the differentiation of IL-4- and IL-13-producing CD4(+) T cells. CD141(+) DCs induce IL-4- and IL-13-secreting CD4(+) T cells through OX40 ligand. Thus, CD141(+) DCs demonstrate remarkable plasticity in guiding adaptive immune responses.

Abstract
Our studies showed that tumor-infiltrating dendritic cells (DC) in breast cancer drive inflammatory Th2 (iTh2) cells and protumor inflammation. Here, we show that intratumoral delivery of the β-glucan curdlan, a ligand of dectin-1, blocks the generation of iTh2 cells and prevents breast cancer progression in vivo. Curdlan reprograms tumor-infiltrating DCs via the ligation of dectin-1, enabling the DCs to become resistant to cancer-derived thymic stromal lymphopoietin (TSLP), to produce IL-12p70, and to favor the generation of Th1 cells. DCs activated via dectin-1, but not those activated with TLR-7/8 ligand or poly I:C, induce CD8+ T cells to express CD103 (αE integrin), a ligand for cancer cells, E-cadherin. Generation of these mucosal CD8+ T cells is regulated by DC-derived integrin αvβ8 and TGF-β activation in a dectin-1-dependent fashion. These CD103+ CD8+ mucosal T cells accumulate in the tumors, thereby increasing cancer necrosis and inhibiting cancer progression in vivo in a humanized mouse model of breast cancer. Importantly, CD103+ CD8+ mucosal T cells elicited by reprogrammed DCs can reject established cancer. Thus, reprogramming tumor-infiltrating DCs represents a new strategy for cancer rejection.

Abstract
In comparison to murine dendritic cells (DCs), less is known about the function of human DCs in tissues. Here, we analyzed, by using lung tissues from humans and humanized mice, the role of human CD1c(+) and CD141(+) DCs in determining the type of CD8(+) T cell immunity generated to live-attenuated influenza virus (LAIV) vaccine. We found that both lung DC subsets acquired influenza antigens in vivo and expanded specific cytotoxic CD8(+) T cells in vitro. However, lung-tissue-resident CD1c(+) DCs, but not CD141(+) DCs, were able to drive CD103 expression on CD8(+) T cells and promoted CD8(+) T cell accumulation in lung epithelia in vitro and in vivo. CD1c(+) DCs induction of CD103 expression was dependent on membrane-bound cytokine TGF-β1. Thus, CD1c(+) and CD141(+) DCs generate CD8(+) T cells with different properties, and CD1c(+) DCs specialize in the regulation of mucosal CD8(+) T cells.

Abstract
Mouse models of human disease form a link between genetics and biology. However, mice and humans differ in many aspects of immune system biology. These differences might explain, in part, why many successful preclinical immunotherapy studies in mice turn out to be unsuccessful when used in clinical trials in humans. Pioneering studies in the late 1980s demonstrated the reconstitution of human lympho-hematopoietic cells in immunodeficient mice. Since this time, immunodeficient mice are being tested as hosts for human hematopoietic organs or cells in an effort to create an in vivo model of the complete human immune system. Such Humouse models could permit us to generate and test novel human vaccines.

Abstract
During viral infection, dendritic cells (DCs) capture infected cells and present viral Ags to CD8(+) T cells. However, activated DCs might potentially present cell-associated Ags derived from captured dead cells. In this study, we find that human DCs that captured dead cells containing the TLR3 agonist poly(I:C) produced cytokines and underwent maturation, but failed to elicit autologous CD8(+) T cell responses against Ags of dead cells. Accordingly, DCs that captured dead cells containing poly(I:C), or influenza virus, are unable to activate CD8(+) T cell clones specific to cell-associated Ags of captured dead cells. CD4(+) T cells are expanded with DCs that have captured poly(I:C)-containing dead cells, indicating the inhibition is specific for MHC class I-restricted cross-presentation. Furthermore, these DCs can expand naive allogeneic CD8(+) T cells. Finally, soluble or targeted Ag is presented when coloaded onto DCs that have captured poly(I:C)-containing dead cells, indicating the inhibition is specific for dead cell cargo that is accompanied by viral or poly(I:C) stimulus. Thus, DCs have a mechanism that prevents MHC class I-restricted cross-presentation of cell-associated Ag when they have captured dead infected cells.

Abstract
Allergic asthma is strongly associated with the airway inflammation caused by the dysregulated production of cytokines secreted by the allergen-specific type-2 T helper (Th2) cells. Interleukin (IL)-12 is a heterodimeric cytokine, which strongly promotes the differentiation of naive CD4(+) T cells to the type-1 T helper (Th1) phenotype and suppresses the expression of Th2 cytokines. Therefore, immunotherapy with IL-12 has been suggested as a possible therapy for asthma. In previous studies, we developed a murine model of airway inflammation based on the purified, house dust-mite allergen Der p 1 (Dermatophagodies pteronyssinus) as a clinically relevant allergen. We hypothesized that the expression of IL-12 in the airway may represent an effective therapy for allergic airway diseases. In this study, we investigate whether the local transfer of the IL-12 gene to respiratory tissues modifies allergic inflammation and airway hyper-responsiveness (AHR) in our disease model. To enhance the in vivo delivery of the IL-12 gene, we expressed the murine single-chain IL-12 protein from a nonviral vector to which the two IL-12 subunits (p35 and p40) were linked by a 14- to 18-amino-acid linker. One of these single-chain IL-12s, containing an 18 amino-acid polypeptide linker, was stably expressed and had a high level of biological activity comparable to that of native IL-12 in vitro. In mice with Der p 1-induced asthma, the local administration of this IL-12 fusion gene into the lungs significantly prevented the development of AHR, abrogated airway eosinophilia, and inhibited type-2 cytokine production. These findings indicate that the local transfer of the single-chain IL-12 gene is effective in modulating pulmonary allergic responses and may be a convenient method for future applications of DNA vaccination.
